# uDisk vs Y

The clearest difference is review sentiment: uDisk at 84% against Y's 9%. uDisk also leads on rating (4.3 vs 2.0). Y's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. uDisk sells 1 one-off in-app purchase. Y asks for nothing beyond the download.

uDisk holds the better App Store score, 4.3 against 2.0. That said, the two scores are not equally well evidenced: Y has 1.7K ratings behind it against 233, so its average is the more settled of the two. Written reviews point the same way: 84% of uDisk's written reviews are positive against 9% of Y's.

uDisk ships an update every 2 months, Y every 3 weeks. The most recent releases landed on September 25, 2026 and September 28, 2026 respectively.
